migrate custom `jssc` dependency to maintainable source used in `serial` library

Problem

While trying to modernize the dependency and migrate it to a Gradle-based setup, this approach as reference:

dependencies {
    compileOnly(project(":core"))
    implementation("io.github.java-native:jssc:2.10.2")  
}

this invoke error methods getPortProperties() that aren't present in java-native/jssc or any other published versions.

because currently, the processing4/java/libraries/serial library depends on a customized version of jssc that is not available on Maven Central or Jitpack . It is documented as a modified version of gohai/java-simple-serial-connector and sampottinger/jssc,

currently migration pull request lives under library/jssc.jar file and is custom-built, and it's a hurdle to issue #1099

Solution

• Create a downstream fork under the foundation org to maintain and publish the custom JAR

• Or incorporate the needed source directly into the repo

Per @Stefterv suggestion, I’m opening this issue to track the long-term resolution of this dependency problem

Comienza leyendo la configuración de dependencias en java/libraries/serial y la biblioteca personalizada library/jssc.jar; después, compara los pull requests referenciados #1189 y #1106 con el uso de getPortProperties(). Se considera terminado cuando la biblioteca serie ya no depende de un JAR personalizado no disponible, manteniendo la API requerida y una ubicación mantenible para la dependencia o el código fuente.
